Light to moderate snow will continue into Saturday over the Great Lakes, Central Appalachians, and Northeast. This weekend into next week, a series of atmospheric rivers will bring gusty winds, periods of heavy rain, and mountain snow to northern California and the Pacific Northwest. Colder temperatures are in store for the weekend from the Great Lakes to East Coast. Read More >
Overview - Atmospheric River - January 26-29,2021
Heavy Rains and Strong Winds Returned to the Bay Area and the Central Coast
|
Water year 2020-2021 was off to an active start in terms of storms generating over the Pacific and moving toward America's Western coastline; however, the La Niña pattern in place kept the storm tracks heading toward Seattle, Portland, and the Pacific Northwest. Any rain received near San Francisco was at the tail end of the system. This resulted in quick, weak frontal systems that only brought light showers to the North Bay, with even less to the South Bay and the Central Coast. Only getting weak fronts kept the Bay Area well below normal precipitation levels and dreaming of a major soaking rain. And then the plume of moisture from the tropical Pacific began to move northward and two magical words were added to the Forecast Discussion: "atmospheric river". (AR) Atmospheric River refresher As an upper level trough moved over the Bay Area bringing strong winds and light showers Sunday, January 24, 2021, a ridge of high pressure was sitting over the southeastern Pacific. The anti-cyclonic rotation of the high pressure pushed a large swath of moisture northward toward Alaska. This moisture would ride around the central high and sink southward toward San Francisco January 26-29, 2021. This "colder" AR is atypical for ARs that impact California. ARs are generally "warmer" and have a more direction connection to Hawaii or the sub-tropics resulting in higher snow levels. The approach of such a large amount of moisture prompted Flash Flood Watches in place for most 2020 burn scars around the area as heavy rain could trigger debris flows and mud slides. Light rain reached the North Bay and San Francisco on Tuesday, January 26, 2021, in the evening. Enough lingering cold air resulted in lower snow levels with accumulating snow over the higher peaks in the Bay Area. In fact, snow levels were low enough that low elevation snow occurred over the Northern Sacramento Valley. As another upper level low started to sink southward, pushing the tropical moisture to San Francisco, a narrow cold-frontal rainband (NCFR) developed on the leading edge that prompted Flood Advisories in the North Bay and a Flash Flood Warning over the Walbridge burn scar. The band moved quickly southward prompting further Flash Flood Warnings over the CZU Lightning Complex, River, Carmel, and Dolan burn scars. High Wind Warnings for higher elevations and a Wind Advisory for valley locations were issued as southerly winds ahead of the NCFR intensified. Gusts in the valleys reached 25-35 mph with higher peaks reaching gusts from 60-80 mph Tuesday evening through Wednesday morning. While rain around the Bay Area tapered off behind the NCFR, it slowed over the Big Sur Coast as it began to encounter higher pressure located west of San Diego. The moisture "hose" was turned on and it was pointed straight at the Central Coast. The main band of precipitation then began to retrograde through the day on Wednesday into Thursday once again reaching the Santa Cruz Mountains. The wavering moisture plume resulted in steady moderate to heavy rain from Big Sur to Santa Cruz on Wednesday and Thursday. As the low pressure moved southward down the coast, the main moisture plumed moved south and inland to the Central Valley bringing snow to the high Sierra, leaving scattered showers around the Bay Area and the Central Coast Thursday evening into Friday. This atmospheric river was the strongest storm of the water year thus far. For total precipitation amounts, see the tab below. Despite this heavy rain, the result keeps much of the Bay Area 40% to 60% of normal precipitation for the water year. While it certainly made a chunk in the deficit, summer remains just around the corner with the hope of more rain before the dry season arrives.

Gusty Onshore Winds
As the leading cold front moved down the California Coastline, winds sharply changed direction to be out of the south-southeast and increased in magnitude. Winds at the valley floors gusted from 25-35 mph with max gusts approaching 40 mph. Higher elevations saw stronger southerly gusts between 60 to 70 mph with Mount Diablo reaching 80 mph gusts!

Debris/Mud Flows and Flooding
Mudflows near the River Fire burn scars covered roadways and trapped animals at local ranches. Heavy rain caused flooding near the Carmel Lagoon, which by Thursday the 28th was breached. Debris flows in Big Sur resulted in the closure of Highway 1, as mud covered pockets of roadway. By Thursday the 28th, a section of Highway 1 near Rat Creek collapsed and fell into the Pacific.

Atmospheric River January 26-29, 2021
Tropical moisture from over the Pacific moved eastward and set up along the Central Coast. This this provided strong winds with reports of snow at higher elevations, a few lightning strikes, but the main impacts were from the copious amounts of heavy precipitation causing ponding and urban flooding as well as debris flows in Monterey County. Flash Flood watches were issued ahead of the event, while Flash Flood Warnings for the Walbridge, CZU Lightning Complex, River, Carmel, and Dolan burn scars were issued during the event as heavy rain rates increased. Event total precipitation totals ranged from 1.5 inches to 2.5 inches in the North Bay Valleys with the higher elevations of the North Bay Mountains received between 3 inches to 6 inches. Downtown San Francisco received 2 to 3 inches. The East Bay ranged between 2 inches to 4 inches, the South Bay 2 inches to 3 inches with the Santa Cruz mountains receiving 8 to 10 inches. By far the most rain was down the Central Coast. Monterey Valleys saw 3 to 4.5 inches with the Big Sur Coast getting between 10 and 13 inches. But it was the higher elevations of the Santa Lucia's that received between 15 inches and 20 inches.
